Guys, help me out. This new iPhone 4S will only have one version for the entire world? It will work in both GSM and CDMA networks (Europe vs. North America)? If yes, then a phone purchased in Canada for example, will work on an European carrier (if unlocked, of course)? Another question: next Wednesday when iOS 5 comes out, will it be again like the iPhone 4S pre-orders? In USA it start at mid-night but in Europe it didn't (basically it start when it was mid-night in USA and here morning already). One more regarding Apple Care: I will purchase an iPhone 4S very soon and I'd like to know if I need to extend my warranty the moment I register the phone online or if I can extend it just days before the 1 year warranty expires? Thank you all.
